is the PPE that is being
used adequate to protect against the risk?
eg there are different types respiratory
protection for different types of contaminant
(vapour, dust etc). It is essential that
you determine the level of protection needed
to ensure that the correct type is selected.
In order to determine the Protection Factor
(PF) of the RPE it is necessary to make
the following calculation:
| PF
= . |
Contaminant
concentration outside the mask |
|
| Contaminant
concentration inside the mask |
It should also be remembered that the PF
of any device is dependant on the level
of leakage around the mask. Leakage varies
significantly, depending upon how well the
mask fits the person and the motivation
of the individual to use it properly. Making
them understand the risks rather than merely
instructing them to wear it is the key issue
here. |
